Surely there is more that 4% of python programmers on windows, even more in machine learning and data science areas, where windows and MacOS X rule (apparently being only 7% of PIP downloads).

[issue42173] Drop Solaris support
Jesús Cea Avión added the comment: I think Solaris Support is still important and I could invest more time on it. About package downloads: 1. I routinely download packages in my laptop (Linux) and distribute them to a fleet of servers (Linux and Solaris) via ansible and similar. Many servers in intranets don't install packages directly via PIP. 2. Under OmniOS or SmartOS (Illumos distributions), many people use the system package manager to install Python packages, not "PIP". For instance, http://netbsd.2816.n7.nabble.com/WIP-commit-Upgrade-to-Mailman-2-1-34-td427426.html. Buildbots: I used to manage a buildbot with OpenIndiana, but it didn't survived the GITHUB migration. I could provide now a SmartOS buildbot. As a core developer, I do care about Solaris. I fully realize I have been quite inactive since the github migration. My fault. I could devote more time to the task. -- ___ Python tracker <https://bugs.python.org/issue42173> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue38301] If "_REENTARNT" is defined in the header file, we should use "-D_REENTRANT" when compiling
New submission from Jesús Cea Avión : When compiling on Solaris family, we define "_REENTRANT" in "Pyconfig.h". That file is included when compiling C extensions, but if the extension is made of several C files, it could be included only in the file that interfaces with python runtime. Unfortunately, "_REENTRANT" modifies the way C code is compiled, so compiling a C extension with some source files with "_REENTRANT" and some other without that "define" can produce bizarre errors and crashes. One example: https://github.com/joyent/pkgsrc/issues/207 In particular, "include" order can make a big difference: https://github.com/jnwatson/py-lmdb/issues/213 I suggest that when "_REENTRANT" is defined in "Pyconfig.h", Python C extensions compilation machinery adds "-D_REENTRANT" to the compilation flags.

New submission from Jesús Cea Avión : Try this in a terminal: """ import gc import concurrent.futures executor = concurrent.futures.ThreadPoolExecutor(999) def a(): 1/0 future=executor.submit(a) future.result() # An exception is raised here. That is normal gc.set_debug(gc.DEBUG_SAVEALL) gc.collect() gc.garbage """ You will see (python 3.7) that 23 objects are collected when cleaning the cycle. The problem is the attribute "future._exception". If the exception provided by the "future" is raised somewhere else, we will have reference cycles because we have the same exception/traceback in two different places in the traceback framestack. I commonly do this in my code: """ try: future.result() # This will raise an exception if the future did it except Exception: ... some clean up ... raise # Propagate the "future" exception """ This approach will create reference cycles. They will eventually cleaned up, but I noticed this issue because the cycle clean up phase was touching big objects with many references but unused for a long time, so they were living in the SWAP. The cycle collection was hugely slow because of this and the interpreter is completely stopped until done. Not sure about what to do about this. I am currently doing something like: """ try: future.result() # This will raise an exception if the future did it except Exception: if future.done(): del future._exception raise # Propagate the exception """ I am breaking the cycle manually.

[issue32660] Solaris should support constants like termios' FIONREAD
Jesús Cea Avión <j...@jcea.es> added the comment: Solaris has two personalities: System V and BSD. This is not usually an issue but sometimes some constants have a different value in a mode or the other. By default, when including Solaris is in System V mode. We can force BSD mode defining symbol "BSD_COMP". This greatly expand the names available but, unfortunately, some values change. The comment in is quite clear: """ * There are some inherent problems in having a single file * ioctl.h, with both System V and BSD flags. Introducing * BSD flags into this file creates compilation problems * with flags such as ECHO, NL1 etc., if termio.h and ioctl.h * are included by the same file. Since these two files can * be only included by System V applications, /usr/inclule/sys/ioctl.h * will be System V mode and all the BSD flags will be turned off * using #ifdef BSD_COMP. This file will also exist in * /usr/ucbinclude/sys/ioctl.h for BSD applications but without the * BSD flags turned off. System V appliactions can use ioctl.h without * any changes, System V applications requiring BSD flags should * -D BSD_COMP when compiling (and be warned about the common * flags between System V and BSD) and BSD applications should * use /usr/ucbinclude/sys/ioctl.h. """ Using "gcc -dM -E" we can observe defined symbols. Ambiguous values when defininf "BSD_COMP" are: BS0, BS1, CR0, CR1, CR2, CR3, ECHO, FF0, FF1, FLUSHO, NL0, NL1, NOFLSH, PENDIN, TAB0, TAB1, TAB2, TOSTOP, XTABS. Sounds quite important, actually. Since I am no aiming to perfection, I would be satisfied making quite a few new symbols available, not all of them. A simple approach would be to include and . In those header files there are only constants, not functions or data structures.

[issue23098] mknod devices can be 32 bits
New submission from Jesús Cea Avión:
Dan MacDonald told me that os.mknod() should accept devices 32 bits.
I wrote this code in linux 64 bits:
#include sys/types.h
#include sys/stat.h
#include fcntl.h
#include unistd.h
#include stdio.h
int main(void) {
printf(%d, sizeof(dev_t));
return 0;
}
The result of running this is 8. We need a long long.
I did this change in Python 2.7 branch:

Looks like this patch is trivial. Please, comment.

[issue23004] mock_open() should allow reading binary data
New submission from Jesús Cea Avión:
mock_open(read_data=b'...') gives an error:
Traceback (most recent call last):
File z.py, line 6, in module
print(f.read())
File /usr/local/lib/python3.4/unittest/mock.py, line 896, in __call__

File /usr/local/lib/python3.4/unittest/mock.py, line 2244, in
_iterate_read_data
data_as_list = ['{}\n'.format(l) for l in read_data.split('\n')]
Easy to reproduce:
from unittest.mock import mock_open, patch
m = mock_open(read_data= b'abc')
with patch('__main__.open', m, create=True) :
with open('abc', 'rb') as f :
print(f.read())
Looks like this bug was introduced as result of issue #17467. I add those
people to the nosy list.

[issue21797] mmap read of single byte accesses more that just that byte
Jesús Cea Avión added the comment: Kevin, mmap is not appropriate for your use. Looks like writing your own module would be simple enough. If performance is not a problem, maybe ctypes/cffi pointer magic encapsulate in your own custom class would be enough for you. I mark this bug as not a bug since you are using mmap+python outside of specs. Feel free to reopen if you don't agree but, please, provide a rationale. -- nosy: +jcea resolution: - not a bug status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21797 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue21797] mmap read of single byte accesses more that just that byte
Jesús Cea Avión added the comment: You could even use ctypes to access the underlining mmap OS syscall. But accessing individual bytes using native python is not guaranteed to work because python is too high level for that. For instance, it could read 64 bits (a word) to only use 8 at the end. I recommend you to write a tiny C module or investigate ctypes/CFFI pointer access to a native mmap-ed area.

[issue21744] itertools.islice() goes over all the pre-initial elements even if the iterable can seek
New submission from Jesús Cea Avión: If L is a big sequence and I do itertool.islice(L, 100, None), islice will go over a million elements before returning the first that I actually cared. Since L is a sequence, islice could go directly to the element 100. My program performance improved hugely replacing a for i in L[p:] for for i in (L[p] for p in range(p, len(L))). Using itertools and doing for i in itertools.islice(L, p, None) is massively inefficient. -- components: Extension Modules messages: 220417 nosy: jcea priority: normal severity: normal status: open title: itertools.islice() goes over all the pre-initial elements even if the iterable can seek type: enhancement versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21744 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
